Isn't cancer a 'rich world' disease?

While cancer is common in the Western world, more cases are seen in developing countries and it is these nations that will see the biggest rise in the future.

More than 60% of the world's total cases occur in Africa, Asia and Central and South America.

And these regions account for about 70% of the world's cancer deaths - a situation that is made worse by the lack of early detection and access to treatment.

Annual figures include donations by private donors and governments for prevention and treatment. Spending by recipient countries not included. More than 90% of cancer funding is spent on anti-tobacco campaigns.
